How do children learn generalizations and exceptions?
Our approach:
For each language:
stem + correct ~ age, stem + overregularized ~ agestem + correct ~ verbs, stem + overregularized ~ verbs
Morphology learning is more strongly related to vocabulary size than to age
For each language and measure:
says ~
how does morphology learning…
verbs + verbs² +
depend on vocabulary size?
age + age & verbs + age & verbs² +
change with age?
(1 + verbs + age | item)
differ for different verbs?
stem + correct: says go and went, doesn’t say goed/wented
stem + correct: says go and went, doesn’t say goed/wented
stem + correct: says go and went, doesn’t say goed/wented
stem + correct: says go and went, doesn’t say goed/wented
stem + correct: says go and went, doesn’t say goed/wented
stem + correct: says go and went, doesn’t say goed/wented
stem + correct: says go and went, doesn’t say goed/wented
stem + overregularized: says go and goed/wented
stem + overregularized: says go and goed/wented
stem + overregularized: says go and goed/wented
stem + overregularized: says go and goed/wented
stem + overregularized: says go and goed/wented
stem + overregularized: says go and goed/wented
stem + overregularized: says go and goed/wented
Verbs that are correctly inflected more are overregularized more
For verbs whose correct inflection is more influenced by vocabulary size, overregularization is also more influenced by vocabulary size
For verbs for whose correct inflection is more influenced by age, overregularization (might be) less influenced by age
